What is similar about elements in aGroup (column) on the periodic
table?
1. Elements in a Group (column)
have similar physical andchemical properties.
2. This means elements in aGroup are more like eachother than any
other
element!

What are 3 examples of
Physical Properties?1.How an element looks or feels( soft? hard? shiny? dull? malleable? brittle? ductile? )
2.Atomic structure(how many protons? neutrons? electrons?)
3.Conductivity(good conductor of heat? of electricity?)

What is 1 example of a
chemical property?
The reactivity of an element when itcombines with other elements. It has todo with the valence electrons.
(does it explode? does it make a new chemical? does itproduce light? maybe it does nothing!)

20/22
Group 18: Noble Gases
1. Colorless and odorless2. 8 valence electrons theyhave a full outer orbital, thisis why they dont react
3. Inert gases meaning theyare unreactive with otherelements!
